Answer in units of C

To calculate the net charge on a substance, we need to find the difference between the total positive charge (from protons) and the total negative charge (from electrons) in the substance.

First, we need to determine the total charge contributed by protons and electrons separately. The elemental charge, given as 1.6 × 10^-19 C, represents the charge of each proton or electron.

The total positive charge is calculated by multiplying the number of protons (8.9 × 10^13) by the elemental charge:
Total positive charge = (8.9 × 10^13) * (1.6 × 10^-19 C)

Next, we calculate the total negative charge by multiplying the number of electrons (2.6 × 10^13) by the elemental charge:
Total negative charge = (2.6 × 10^13) * (1.6 × 10^-19 C)

Finally, to find the net charge, we subtract the total negative charge from the total positive charge:
Net charge = Total positive charge - Total negative charge

Now, let's calculate it step-by-step:

Total positive charge:
= (8.9 × 10^13) * (1.6 × 10^-19 C)
= 1.424 × 10^-5 C

Total negative charge:
= (2.6 × 10^13) * (1.6 × 10^-19 C)
= 4.16 × 10^-6 C

Net charge:
= Total positive charge - Total negative charge
= (1.424 × 10^-5 C) - (4.16 × 10^-6 C)
= 9.08 × 10^-6 C

Therefore, the net charge on the substance is 9.08 × 10^-6 C.

To calculate the net charge on the substance, you need to find the difference between the total positive charge (protons) and the total negative charge (electrons).

Given:
Number of protons (positive charge) = 8.9 × 10^13
Number of electrons (negative charge) = 2.6 × 10^13
Elemental charge = 1.6 × 10^-19 C

To calculate the net charge:
1. First, calculate the total positive charge by multiplying the number of protons by the elemental charge:
Total positive charge = (Number of protons) x (Elemental charge)
= (8.9 × 10^13) x (1.6 × 10^-19 C)

2. Next, calculate the total negative charge by multiplying the number of electrons by the elemental charge:
Total negative charge = (Number of electrons) x (Elemental charge)
= (2.6 × 10^13) x (1.6 × 10^-19 C)

3. Finally, calculate the net charge by subtracting the total negative charge from the total positive charge:
Net charge = Total positive charge - Total negative charge

Please perform these calculations to find the net charge in units of C.
